[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] A switching power supply protective housing, comprising:

[0028] A housing 1; a top cover 2 is mounted on the top of the housing 1 by fixing screws, and a mounting plate 4 for mounting a power module is provided on the inner bottom of the housing 1, and a mounting hole is provided on the mounting plate 4;

[0029] A heat dissipation port 3 is provided on the top cover 2, a dustproof mesh plate 6 is clamped on the top of the shell 1, and the top surface of the dustproof mesh plate 6 is attached to the bottom of the top cover 2. A convex pipe 11 connected to the interior of the shell 1 is provided on the outer wall of one side of the shell 1, a fan 12 is installed inside the convex pipe 11, and a mesh surface 14 for dust prevention is provided at the end of the convex pipe 11.

[0030] A top cover 2 is installed on the shell 1, and a mounting plate 4 with mounting holes is provided in the shell 1 for installing the power module. A heat dissipation port 3 is provided on the top cover 2, and a dustproof mesh plate 6 is provided in the top cover 2 shell 1 below the top cover 2. In addition, a convex pipe 11 with a fan 12 inside is provided on the outer wall of one side of the shell 1, and a mesh surface 14 for dust prevention is provided at the port of the convex pipe 11. When in use, the power module is installed on the mounting plate 4 in the shell 1. The power module generates heat when working. The fan 12 can draw external air into the shell 1 and discharge it through the heat dissipation port 3 on the top cover 2. In this process, the heat in the shell 1 can be taken away. At the same time, the mesh surface 14 at the port of the convex pipe 11 can prevent external dust from entering the shell 1 through the convex pipe 11, and the dustproof mesh plate 6 can prevent dust from entering the shell 1 through the heat dissipation port 3.

[0031] In general, the device has a simple structure and is easy to use. The power module can have good ventilation and heat dissipation effects in the shell 1 to avoid heat accumulation inside the shell 1. At the same time, it also has a good dustproof effect, which can prevent external dust from entering the shell 1 to cause damage to the power module, providing a good working environment for the power module.

[0032] For further information, see Figure 3 :

[0033] The upper inner wall of the housing 1 is provided with a peripheral edge 5, and a sealing groove 7 is provided on the peripheral edge 5. A sealing ring 8 is provided at the bottom of the dustproof mesh plate 6, and the sealing ring 8 corresponds to the sealing groove 7. Through holes 9 for fixing screws to pass through are provided on the frames of the top cover 2 and the dustproof mesh plate 6, and screw holes 10 corresponding to the fixing screws are provided on the peripheral edge 5.

[0034] The top cover 2 and the dust screen 6 can be installed simultaneously by sequentially passing the lower end of the fixing screw through the through hole 9 on the top cover 2 and the through hole 9 on the dust screen 6 and then threading them into the screw hole 10 on the surrounding edge 5. Conversely, the dust screen 6 and the top cover 2 can be removed at the same time by removing the fixing screw, which simplifies the installation steps of the two components in the device, making it easy to inspect the power module inside the housing 1 and remove the dust filter for cleaning.

[0035] When installing the dustproof mesh plate 6, the dustproof mesh plate 6 is attached to the surrounding edge 5, and the sealing ring 8 at the bottom of the dustproof mesh plate 6 is just inserted into the sealing groove 7 on the surrounding edge 5, which not only plays a positioning role, but also can avoid the existence of a gap between the dustproof mesh plate 6 and the surrounding edge 5, thereby improving the dustproof ability.

[0036] For further information, see Figure 4 :

[0037] A pipe sleeve 13 is threadedly installed at the end of the convex pipe 11 , a mesh surface 14 is arranged inside the pipe sleeve 13 , and a shifting block for rotating the pipe sleeve 13 is arranged at the edge of the pipe sleeve 13 .

[0038] By arranging the mesh surface 14 in the pipe sleeve 13, and the pipe sleeve 13 is installed on the end of the convex pipe 11 by threaded connection, the mesh surface 14 can be easily removed for cleaning, and the fan 12 in the convex pipe 11 can also be easily inspected and repaired.

[0039] Also, see Figure 1 , Figure 4 and Figure 5 :

[0040] Two groups of mounting plates 4 are symmetrically arranged at the bottom of the housing 1, and a gap is arranged between the bottom of the mounting plates 4 and the bottom of the housing 1, and protective plates 15 are arranged on the outer walls of both sides of the housing 1. The mounting plates 4 are sealed and plugged into the inner wall of the housing 1, and one end of the mounting plates 4 located outside the housing 1 is integrally formed with the protective plate 15, and multiple groups of fins 16 are distributed on the outer wall of the protective plate 15 to improve the heat dissipation capacity.

[0041] After the power module is mounted on the mounting plate 4, since there is a gap between the mounting plate 4 and the bottom of the housing 1, the bottom of the power module also has good ventilation and heat dissipation conditions, thereby improving the heat dissipation capacity;

[0042] A protective plate 15 is integrally formed on the mounting plate 4, and the protective plate 15 is located on both sides of the shell 1. Fins 16 are arranged on the protective plate 15. Through such a design, on the one hand, the protective plate 15 can provide good protection for the shell 1, and prevent external collisions and accidental drops from easily causing damage to the shell 1 and the power module inside the shell 1; on the other hand, the integrally formed mounting plate 4 can conduct heat generated by the power module after contacting the power module, and the fins 16 on the protective plate 15 can achieve good heat dissipation effect, further improving the heat dissipation effect of the present application.

[0043] Among them, in actual use, the mounting plate 4, the protection plate 15 and the fins 16 are an integrated structure made of aluminum alloy.

[0044] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
